[mythtv-users] Red Eye Serial problems with USD to Serial converter

[Kieron Wilkinson]

Hi,

I've been using a Red Eye Serial (www.redremote.co.uk) for a while now
with the Linux program on the download page to work with my Telewest
cable box, and it works very well! However, I have just bought a new
system without any serial ports and so bought a Manhattan USB to Serial
converter (a PL2003 device that I am using with SuSE 9.3 - it did say
something about "DEVPATH is not set" in the /var/log/messages file when
I plugged it in).

After plaugging in the RedEye and changing the device to /dev/ttyUSB0 I
can change channels on my Telewest box. ONCE. It only works once, and I
have no idea why. If I remove the USB adaptor and plug it back again, I
can change channel one more time.

Subsequent attempts to change channel still show the RedEye power being
applied as normal (from the red power light) but the light does not
pulse for the channels being sent like it normally does. It just stays
with power light for roughtly the same amount of time, and then
finishes. There are no errors emmitted by the program.

Has anybody had similar trouble, and perhaps knows how to fix this?

I was wondering if the program was not releasing the serial port
properly or something, though the source code looks to be doing so (bear
in mind that I do not know C). I guess I should be able to build a
script that "unplugs" the device via hotplug and reattaches it so the
channel changes work, but this is not really an ideal solution. ;)

Any help appreciated!
